    What is the normal force required in pound pressure or weight, necessary to engage and/or hold the engagement of a standard clutch for the power unit of most combination vehicles used for interstate transport of freight?

    Are asking about how much it takes to depress the pedal? That would vary depending on the design of the linkage and would change for different truck models.

    Sounds like he's asking spring pressure.

    In an Eaton example it mentioned clutch plate load of 3,200 lbs. That would be my best guess at an average pressure to clamp the discs.

    If that's the case it would vary by clutch torque rating, a 2050 for example has a clamp load of 4000lbs. It is usually listed in the clutch specs on the manufacturers websites.

    Sorry ... I should have been more precise. What I meant is the measured force/pressure/weight required from the human leg to depress/engage the clutch and/or keep it engaged.

    A range of force/pressure/weight would suffice to encompass the various models of truck out there ... a range from highest exertion level to the least will do. Thanks

    I doubt very much if anyone has information about that.

    Depressing the pedal disengages the clutch. Otherwise it is always engaged.



    English language - not everyone's cup of tea!
